I know the Poser 4 (and 6) lighting basics: i.e the different types of lights, and what each light type's properties do. However, properly lighting an image to my satisfaction takes me even longer than posing! At this point in time, I think I spend too much time trying (and adjusting) various lighting setups until I get something that looks nice.

Are there any tutorials out there on how to create dramatic lighting in images (preferably, but not necessarily for poser)? I don't need tutorials on what the lighting types and dials are (I know that already), but on how to make the lighting dramatically & asthetically pleasing. Hopefully with well-lit examples (there's nothing more disconcerting than a tutorial with sample images that are worse than one's own art!).

Thanks!
